These include Liverpool One, which is slated to open next year with 1.65 million square feet of retail on a 42-acre site in that northern British city center; the expansion of the existing Broadmead retail center, in downtown Bristol, to 1.7 million square feet of retail; and the 2008 opening of Westfield London, a 1.65 million-square-foot center in the Shepherd's Bush section of the city.

其中包括Liverpool One，预定明年开业，有165 万平方英尺零售面积，占地42 英亩，位于英国北部城市中心，是由现有的Broadmead 零售中心扩建而成；在Bristo 市中心，有170 万平方英尺的零售面积，于2008 年启用的Westfield London；165 万平方英尺的在Shepherd's Bush 市区的购物中心。

We analyse the characteristic of support vector set and the possible change after new samples are added to training set.

第三，通过概括支持向量集的特点及其在增量学习过程中的变化，我们分析比较了几种现有的SVM增量学习方法，并对它们在中文网页分类器中的性能进行了对比。

The distributive signature and cheat-proof secret sharing scheme are used during the course of the signature in this scheme. Compared with recent RSA digital signature,this scheme has a higher security.

该方案在签名过程中溶入了部分签名和防欺骗的秘密共享方案，相比于现有的RSA签名方案，该方案具有更高的安全性。

In order to process incomplete information systems, the classical rough set theory needs to be extended.

为了能够有效地分析处理不完备的信息系统，必须对现有的Rough集模型进行扩充。

If it were not, and you wanted to reassign a shortcut key combination that is already in use, you must first delete the existing key.

如果不是，你想重新指定一个已在使用的快捷键组合，您必须先删除现有的键。

Using the theory of the combinational chemistry, we have made the problem above almost solved.

该装置 与现有的DNA合成仪相连接，采用标准的流体接口。

Firstly, this thesis introduce the related concepts of the algorithm and some GCD algorithms that current existing, then list a few basic properties of Greatest Common Divisor.

本文首先介绍了算法的相关概念和当前现有的GCD算法，然后列出了最大公因子的几个基本性质。

The first mobile communications network on the condition of the development, and then introduced the GSM editorial system theory, network characteristics, network optimization technology, concentric circle theory and a detailed presentation on the basis of existing GSM cordial applications, and this technology applications and the development prospects.

本文首先介绍移动通信网络的发展状况，然后介绍了GSM网络的系统工作原理，网络特性，对网络优化中同心圆技术的原理进行了详细的讲解及对在现有的GSM网络基础上的应用，并此技术的应用和发展进行了展望。

The application of the lattice Boltzmann method in unsteady open channel flows was studied in detail in the paper. An existing lattice BGK model was mended; For the problem of negative local equilibrium and evolutionary distribution, we proposed a lattice Boltzmann model based on cell-population equilibrium, which is a direct non-negative approximation to the continuous Maxwell distribution. The model reduces the transport and collision, two basic evolution steps in the LB model, to transport of the non-equilibrium distribution.

本文系统的研究了格子Boltzmann 方法在明渠非恒定流中的应用问题，改进了一个现有的LB 模型，数值实验表明此改进是有效的；在平衡态分布函数及分布函数的非负性问题上，作者提出了一个基于单元均衡的格子Boltzmann 模型，通过直接对Maxwell 分布函数的离散化实现对速度分布函数的非负离散，这种方法将传统模型演化过程中的碰撞和输运两个步骤直接表现为粒子的输运。
